We really need help packaging CuteMarkEd. Especially for Linux and Mac OS X. For Linux there is already an openSUSE Build Service project, but it's outdated. Please contact me if you like to help.

We use Transifex for the translations. Currently we have translations for Chinese, Czech, German and Greek. We are always interested in more translations.
